The master thesis has a detailed description of the power of harmonics. A test measurement was performed to show which method of measuring the harmonic power is the most appropriate. After it has been shown that MATLAB is the most suitable one, because only MATLAB shows the phase of voltage and current, measurements were made on a boost converter.
Up to 6 working points were recorded on the boost converter, 3 points were in continuous mode and 3 in discontinuous mode of operation. The input, output and valves power harmonics were recorded. It was found that the input and output of the inverters have negligible waviness and the valve power harmonics have been thoroughly analyzed. Through the analysis it was found that with the reduction of the input voltage the valve losses are increased. The measuring result are commented at the end
